Present

Question 3

Analysis created by doctors Lyle Johnston and Marvin Tanaka

Answer 3

Tanaka and Johnson analysis

Question 4

T&J analysis
In this analysis the mesiodistal width of the upper and lower canines, first and second premolars is determined from the:

Answer 4

Mesiodistal widths of the lower incisors

Question 5

Realiability of T&J analysis

Answer 5

75%

Question 6

5 steps T&J analysis

Answer 6

1. Mesiodistal width of the four lower incisors is measured
2. Mesiodistal width of the four lower incisors is added and divided into two
3. Prediction of the mesiodistal width of the canine, first premolar and second premolar, 10.5 are added to the result of the division of the mesiodistal width of the incisors
4. Predilection of the mesiodistal width of the canine, first and second upper premolars, 11mm are added to the result obtained from the division of the mesiodistal width of the lower incisiors
5. Once the maxillary and mandibular predictions have been obtained it is known what is the space required to adjust the canine and premolars within the arch.

Question 7

If the available space is greater than the required space there will be…

Answer 7

Enough space to place the canine and premolars within the arch.

Question 8
